Why not?
Also yes, her students can read the same tractatus to boost their understanding after she teaches them to the limit of her abilities. They can also gain experience from a tractatus that she writes. So at an ability of 5 she can write 3 tractatus at SQ:12 each if she reads enough tractatus to go from level 5 to level 6 ability this is 30xp worth, so one she finishes teaching her students to level 6 they can read both her tractatus and those she has already read for a total of 66 xp- of which 35 brings them to level 7 and they will have 31xp towards level 8. They would then be able to write 4 tractatus apiece that their teacher could then benefit from in advancing her own knowledge of magic theory, though she might want to spend time as a student first to learn from them to get her MT up to 7 before reading their tractatus.
